o-Nitrobenzaldehyde is photolabile because of an irreversible phototautomerization, whereas comparable aromatic compounds function as photoprotectors because the tautomerization is reversible. In this experimental and theoretical study we track down the cause of this difference to the electronic changes that occur during the tautomerization.
邻硝基苯甲醛由于不可逆的光互变异构而不稳定，而可比的芳香族化合物则作为光稳定剂发挥作用，因为互变异构是可逆的。在这项实验和理论研究中，我们追踪到这种差异的原因是互变异构过程中发生的电子变化。
